Stephen Smalley 6e2bdb770f libselinux, sefcontext_compile: handle NULL pcre study data 
pcre_study() can return a NULL result if no additional information
could be determined for the pattern.  Thus, sefcontext_compile
needs to correctly handle the case where the study data is NULL
when generating file_contexts.bin, and libselinux needs to correctly
handle it when loading file_contexts.bin.  Fix them both.

This change enables:
semanage fcontext -a -t httpd_exec_t "(/.*)?"
to succeed, since the regex itself is valid but there is no
additional information produced by pcre_study().
